Abstract

Procédé et appareil permettant de déterminer un mode de prédiction intra d'une unité de codage. Les modes de prédiction intra possibles d'une unité de codage d'une composante de chrominance, qui comprennent un mode de prédiction intra d'une unité de codage d'une composante de luminance, sont déterminés. De plus, les coûts de l'unité de codage d'une composante de chrominance, en se fondant sur les modes de prédiction intra possibles déterminés, sont comparés pour déterminer un mode de prédiction intra qui présente un coût minimum, ce mode de prédiction intra devenant celui de l'unité de codage d'une composante de chrominance.
